Solution

The correct option is B Bessemeriztion
In the extraction of copper, the self-reduction reaction of Copper taking place in a Bessemer converter is as follows:

$2 C u_{2} S + 3 O_{2} \to 2 C u_{2} O + 2 S O_{2}$

$C u_{2} S + 2 C u_{2} O \to 6 C u + S O_{2}$ (self reduction)
Option C is correct.
